Grid Metals Reports New High Grade Lithium Mineralization at Donner Lake
Grid Metals Reports New High Grade Lithium Mineralization
at Donner Lake
TORONTO, ON / ACCESSWIRE / May 12, 2022 / Grid Metals Corp. (the "Company")
(TSXV:GRDM)(OTCQB:MSMGF) is pleased to report results for three additional holes from the
recently completed Phase 1 drill program at its Donner Lake Lithium property in southeastern
Manitoba. The property is located in the Winnipeg River pegmatite field, which hosts the
world-class Tanco pegmatite. The Donner Lake Lithium Property is a 75%/25% joint venture
between Grid Metals Corp and Lithium Royalty Corp., a leading player in global lithium finance.
Highlights:
• New d rill intersections of the Northwest Dyke include the following length-weighted
average grades:
o 10.3 metres averaging 1.0% Li2O in GDL22-04, including a higher-grade section of
5.1 metres averaging 1.8% Li2O (from 234.1 metres)
o 12.9 metres averaging 1.0% Li2O in GDL22-08, including higher-grade sections of
1.8 metres averaging 1.8% Li2O and 3.0 metres averaging 1.6% Li2O (from 163.1
metres)
o 9.6 metres averaging 0.8% Li2O in GDL22-09 including 2.9 metres averaging 1.5%
Li2O (from 104.9 metres)
• Anomalous cesium and tantalum values are also present in the three holes including
maximum values of 210 ppm Ta2O5 and 341 ppm Cs2O over 0.6m from the Northwest
Dyke in GDL22-08, and up to 400 ppm Ta2O5 and 481 ppm Cs2O over 0.3m and 0.5m,
respectively, from an adjacent, narrower felsic dyke intersected in hole GDL22-09.
• The Northwest Dyke has now been traced for ~600 meters along strike and drill tested to
a vertical depth of ~250 meters.
• The Northwest Dyke features consistent lithium grades that are associated with visible
spodumene crystals and/or spodumene-quartz intergrowths (‘SQUI’).
• The Northwest Dyke is the second drill-defined LCT type pegmatite with significant strike
length on the Donner Lake property. Similar lithium grades were previously reported for
the Company’s 2018 drill holes targeting the Main Dyke, which is located ~1.5 km to the
east of the Northwest Dyke.
• The Company concluded its Phase 1 exploration drill program targeting the Northwest
Dyke on April 30, 2022. Sixteen (16) drill holes were completed and results for eight (8)
holes have now been reported. Assay results for the remaining eight (8) holes are
pending.
• The Northwest Dyke remains open along strike in both directions and at depth.
Note that the Northwest Dyke intersection lengths reported above do not represent the true
thickness of the dyke, which is estimated to typically range from 4 to 8 metres, representing 50-
70% of the reported intersection lengths. Complete analytical results for hoes GDL22-4, -08
and -09, together with drill hole specifications for these and previously reported holes, are
provided in the Appendices accompanying this release. Hole locations are shown on the
accompanying plan view map and longitudinal section.

Lithium Property showing the current surface projection of the main pegmatite body (thick pink line) and

(GDL22-04, 08 and 09) holes.
Mr. Carey Galeschuk, Grid’s Vice President, Lithium Exploration, stated, “Grid is pleased to see
very consistent and high grade lithium values at the Northwest Dyke from our recently
completed drilling. With continued success we will focus on rapidly establishing a maiden
resource from both the Northwest and Main Dykes at the Donner Lake Property. We also see
great upside in the exploration potential of the property as the Winnipeg River pegmatite field
hosts the world class Tanco Pegmatite and Canada’s only producing lithium mine. We will
shortly be announcing plans for a property-wide geological mapping and geochemical survey
program to enable the discovery of other lithium-bearing pegmatites on the Donner Lake
property."
About the Donner Lake Lithium Property
• The Property is owned 75% by Grid Metals Corp. and 25% by Lithium Royalty Corp.
(LRC), which is funding 25% of the current exploration program. LRC holds an overriding
2% royalty on the property.
• The Property was acquired by Grid from Tantalum Mining Corporation of Canada
Limited (Tanco) which has the first right to acquire products produced from the
property at commercial terms and holds a 2% royalty on certain claims.
• Sinomine Canada is currently operating a lithium spodumene circuit at its Tanco Mine
facility, located approximately 35 km to the southwest of the Donner Lake Property.
• The Donner Lake Lithium Property is only 180 km from the provincial capital of
Winnipeg. It is accessible by all season roads and logging trails and there is nearby
access to Canada’s major east-west railway line.
• Grid Metals has an exploration agreement in place with the Sagkeeng First Nation,
whose Traditional Lands include the Donner Lake and Mayville properties.
• The Property has nearby access low-cost renewable power from Manitoba’s extensive
hydro-electric grid.
• There are multiple LCT-type pegmatite dykes on the Property including the Main Dyke
that, in 2018, was drill tested by Grid over a ~1 km strike length. The dykes are located
along a ~9 km long prospective geological contact between the Bird River greenstone
belt and the Makwa Lake batholith and occupy obvious structural trends.
• The Main Dyke and Northwest Dyke together supported a non -compliant historical
resource estimate of 3.8 million tons at a grade of 1.28% Li2O (Manitoba Mines Branch
Assessment file 91769A). This resource estimate cannot be independently verified by the
Company. The Company plans to resume drilling as soon as possible to establish a maiden
NI 43-101 lithium resource and continue exploration for other LCT -type pegmatites on
the Property.
• The Property is significantly underexplored with a large portion of the prospective
geology having seen no prior lithium exploration.
Quality Assurance and Quality Control
Grid Metals applies best practice quality assurance and quality control ("QAQC") protocols on all
of its exploration programs. For the Donner Lake drilling program, core was logged and sampled
at the Company’s core facility located on the Makwa Property. Generally, 1.0 metre sample
lengths were used. Samples were bagged and tagged and then transported by secure carrier to
the Actlabs (Thunder Bay) laboratory for sample preparation and analysis for lithium, cesium,
tantalum and selected major and trace element abundances using a sodium peroxide fusion total
digestion method followed by ICP-OES and ICP-MS analysis. The Company is using two lithium +
rare metal certified reference materials ("CRMs") and two analytical blanks for the Donner Lake
program to monitor analytical accuracy and check for cross contamination between samples.
